The time-evolution Monte Carlo simulation code DYACAT is applied in order to investigate the depth profiles of big cluster impacts on amorphous targets, using three different cluster-target combinations. For (Ag), cluster impacts on A1, the recoil A1 atoms clear the way for the cluster Ag atoms coming afterwards. The projected range of an (Ag)500cluster is about four times larger than that of a monoatomic ion. In the case of the (Al)ncluster impacts on Ag, the clearing-the-way effect is not so large if n < 100, and the frontrunners are the cluster atoms in the lower part of the cluster. In the case of the (D)<ncluster impacts on Ag, there is no clearing-the-way effect. The projected range of a big (D)ncluster is slightly less than that of the monoatomic ion due to the enhanced energy removal at the surface.
